Specification of Letters Patent. Patented J an. 10, 1911.

Application sied may e, 19,10.r seria'i 1101559334.-

f Be it known that I, GEORGE B. KINsLEl, a citizen of the United States, residing't State of Connecticut',` have invented certain new and useful Improvements in.Univ ersal Joints, of which the following is a specification.

used with advantage in many different connections.

One ofthe purposes of the invention is to provide a joint which is thoroughl stron Another object is to providefor ong l1 e thereof and a further one is afmeans for frmlyliolding in position the divided rings or clamps which are generally utilized to hold the vterminal members of the cover or casing in place.y

The apparatus involves other featuresof novelty and advantage, which with the foregoing will-be set forth at lengthin the f0l-y lowing description wherein I will outline in detail that. form Aof embodiment of the invention which I have selected for illustration, in the drawings accompanyingand pressed in said claims.

-volving my invention.

forminv part of' the present specification. From t. ie statement just made it will be understood that I do not restrict myself to the showing made by said drawings and description; I may depart 'materially therefrom within the' scope of my invention as ex- I also wish'to indicate that it is not essential that all the improvements be used in a joint.

Referring to sa'd drawings: Figure l is a longitudinal sectional view ofa joint -in- Fig. 2 is an end view partly in section of thesume, and, Fig. 3'is :t detail View of the coupling member Aof the device.

Like characters lefcr to like parts .'My joint com rises vthree main members "as 2, 3, and 4, tie members 2 and 3 being practically duplicates and the member 4 constituting a coupling, the coupling'memb'cr serving throughthe aid of certain parte for uniting the two members2^and 3 for rela tive swinging movement about transverse axes .vv/hereby'` the desired relative universal movement of 'either or both of lsaid mem? bersv 2 fand 3 can be secured.- Itv does not matter which of the members 2 and 3 is the This invention relates to 'universal joints and a device involving my invention can be driving oi' power applying one. The members 2 and 3 are shown rovided at theii` inner. end s';A with forks eac i denoted by 2 a fd wliiclrare as customary disposed at right anglesto each other, said` forks being so niounted that each brancher arm thereof is supported upon opposite sides of the saine whereby a strong structure isassurcd. The

'coupling member 4 is of suoli characteras will hereinafter appear, as to provide foi.l thus supportingthe two forks.

y'The two' members -2 and 3 may be connected with the intermediate coupling inem- .ber iii anyndesirable manner, although the means shown forthispurpose will be hereinafter described.` The cou ling member in- 'cludesa body as 6 und a though it is conceivable Athat i this l) slots hereinaftei'-deseribed, might be solid or inipei-forate, 4I prefer for the sake 'of ody, except for-certain liglitnessto makeiit in the forin of a skele f ton or'spider likeplate. The bod""6, as

shown, ,has foursubstantia'lly 'radia ly d is-v posed arms and fa .central 'opening, this re-V lation assuring the desiredliehtness without sacrificing strength. the body or plate 6 ywhich'islpreferably integral has four equidistantly disposed slots 7 which are preferably'formed in and extend entirely through the armsLto` which I have already alluded.. These slots' receive hubsnas 3' at the outerends of the branches of the two main members 2 and 3. These hubs' fit the slots. somewhat closely transversely thereof', so that siii ihubs wil be supported at their opposite si ies,- although the slots 'are some`.

what elongated which permits free oscillation of the tuvo members 2 and V3 abouttheii" Abushingsl) and these bushings receive pivotsus`10 which may, as shown, oo iisistof :pins extending throughbores 11i the'phite Any .lateral movement of the two said` oi' body 6 and also through the rim or. flan c4 A portion 11 surrounding said plate.. Wh'l e it is not essential, I prefer'tomake tbisplate iii one piecefan'd to alsomake itintegral .with` the rimer-,flange 1l as thereby the 'maximum strengthand rigidity are secured.

Theipivotslll'are preferably stationary, and

they are reinovably,.held in place by pins as 12 4whichl extend through transverse perfo- 'rat-ions or holes in the coupling-.finei'nber 4 Aiio fact t 'Q- f l ceases and ivotsI l respectively.l wing to the lint the pivots do not turn, they are not subjected to unusual wearf which Would be the case were they to rock in their bearings. The bushings 9 take u .the Wear, and

"as .said bushings are remova le, it becomes a simple matterto remove the worn parts or any. oneofvthem by withdrawing the necwhich I have referred and which may lcon-- sist of bolts. The two parts of the central portion 13 are' closely fitted to and lover the peripheral A portion of the rim or lxange 11" sothat said central portion is rigid tvith said rim, Owingto the-fact that the tiangeor rim 11 is circular, itpractically, acts as part -of: the coveror casing in that it closes the gap-between the adjacent edges ofthe two;

' parts of the central portion 13. There is novdirector positive connection between the terminal sections let o f the casing orhous-` ing and the central part thereof, owing to Vthe fact that saidfterminal portionshave a.

universal contact with the said-"central or 'intermediate portion.

I provide means for rigidly holding 'the yterminal'ca'sing sections 14 to the respective members 2 and 3 and if this means is 'described in connection -withone, it will ap` ply to the other, as the saine are of similar construction, and in this connection reference Willbe had to the member 2 and its immediate spherical casing section 14. At.

the junction betweenthe fork and' shank of said driving member-2 there is shown an annular shoulder 16 against which fits the flattened portion 17 of the coperating part 14, said part 14 being held to the member 2 byheing pressed against thcsaid shoulder 16, and for 'this .purpose the divided collar or clamp 18 maybe provided, said clamp fitting against the circular Ailange19 on the i' shank or shaft portion of the vsaid member 2, and the, parts thereof being connected to# gether by screws 20. It is conceivable that -vthis collarmiight be threaded onto the shank or shaft portion of said driving member 2,

but this is not "ery desirable in that the Vcollar in such a case -will backofl",thereby jpermitting'the w rating casing portion 14 to loosen, and ence rattle., It. is also possible that in theconstruction which I eming the collar in position, for example, .loe- A tween the flange 19 and 'the coperatin" casing portion-14; The flange 19 has onf-rits inner side awedge or taper face 21 which co 7 Pl'oy, the screivs Qoimay be loosened, but

provide a means which vvill prevent the collar fromv being turned t'o any annoying extent even should nuts of ltssecuring, bolts 2O be accidentally loosened. Thisconstruc- 70 tin I obtained in the present case; b y wedgoperates with a Wedge or taper face 22 of substantially'similarpitch upon' the outeipv I' side of the clamp 18. Whenthe'cl'amp 'is drawn closed by -the action o`f its screws 2Q,

` the collar or clamp 18 is most firmly wedged FQ in place, and assaid collar 'bears agalnstf the part 14, the latter will be solidly pressed against its Seaton the shoulderA or bearing 16. I refer that theinternal diameter of the col aror clamp" 18 be greater than the.f5 external diameter of that part ofA the shank orshaft portion of the member 2, between the shoulder 16 and the I iange 19 spas toy vamply compensate for ant;v wear and atfthesame time avoid the necessity, of skilled 90 labor in assembling the parts.
